I have one hunting rifle - Ruger Hawkeye 25-06. This is my only hunting rifle for deer and coyotes. The only rifle that I can use for hunting would be my Mosin Nagant. I also have a Ruger SR762 which I definitley would not want to use to carry in the mountains. Are back hunting rifles really necessary? Aren't rifles,like the Ruger true and tested to last al long time. Is it worth it to buy a back up hunting rifle? If ever, would you suggest another one in a different caliber? I do not forsee myself hunting for bear, elk antelope, etc. Thanks.
